The cysticercosis is a major zoonotic disease in many developing countries. This study was carried out to determine the prevalence of porcine cysticercosis and to identify potential risk factors associated and their seroprevalence as well in Benin. The tongue palpation was performed on 4150 pigs from the pig farmers were randomly selected to diagno...

Owning the best productive animals is among of the production goals of cattle farmers. This study aimed at exploring the selection indicators used by farmers to identify best promising cattle. Data were collected through surveys from 105 cattle farmers identified as Borgou cattle farmers. The data collected enabled to determine the scores and indic...

Benin has been facing the loss of its animal genetic heritage over the years. The aim of this study was to explore the reasons related to the progressive abandonment of the Borgou cattle breed. The assessment of threat level and functional traits related to the Borgou breed was therefore collected through semi-structured interviews from 105 cattle...

Reproductive parameters of dairy animals are generally affected by meteorological factors. This study aimed to investigate the effects of heat stress (HS) on reproductive parameters Saanen and Saanen Red Maradi (½S½RM) dairy goats reared on a private farm in a tropical sub-humid environment in Benin. To assess the reproductive performances 103 goa...

With the view to study the body conformation in Borgou cattle breed, sixteen morphometric measurements were taken on 108 adult Borgou cattle reared at the Okpara Breeding Farm and then submitted to a Principal Component Analysis. The correlation coefficients varied from -0.03 (CP and RL) to 0.89 (BH and HS) and most of them are positive and signifi...

The objective this study was to evaluate the adaptability of Saanen and the crossbreed goats (Saanen-Red Maradi) reared in a semi-intensive system under a moderate and extreme heat stress conditions. The study involved hundred dairy goats, 45 of which were Saanen and 55 half Saanen and half Red Maradi (RM) crosses and was carried out during 2019 an...

Feed intake on pastures plays a vital role in cattle rearing in West Africa. However, the scarcity of pastures during the dry season may result in changing grazing behaviour by cattle. Therefore, we studied the management practices of transhumant herders on communal rangelands through monitoring of cattle herds’ behaviour in southern Benin. We expe...

A thorough knowledge of cattle herding systems is very important for planning sustainable genetic improvement and conservation strategies. This paper is initiated to characterize Benin native Borgou cattle farming systems in its department of origin by mean of survey including 180 cattle farmers owning at least one phenotype of that breed. Using mu...

Livestock production in the changing climatic condition is influencing by heat stress. The study was aimed to establish a heat stress mapping in Benin by means of Temperature-Humidity Index (THI) from 2009 to 2019. THI combines ambient temperature and relative humidity, and help to predict the effects of thermal environment warmth in dairy animals....

A false perception of climate change can lead to lack of adaptation or maladaptation, thus increasing vulnerability to climate change. Nevertheless, very few studies have focused on this question, especially with cattle breeders. This study compares the climate change perception of cattle breeders in the dry and sub-humid tropical zones of Benin wi...

Pastoral livestock farming systems effectively promote a highly constrained agro-climatic territory, they are both a source of protein and income for the majority of poor people in Africa. At the same time, climate change is a threat to livestock farming because of the impact on animal performance and the quality and availability of pastoral resour...

Filling information gaps is important for setting future research priorities and defining proper strategies for the improvement and conservation of indigenous breeds. This review focuses on a synthesis of knowledge on the Borgou cattle breed farming in Benin. It gathers information about its origin, its physical and ethnological characteristics. It...

Djidja est l’une des plus grandes communes productrices agricoles du département du Zou au sud du Bénin. De par ses ressources fourragères et hydriques, elle est devenue une destination des éleveurs transhumants. Les mouvements des éleveurs transhumants continuent de s’étendre, de même que les séjours dans cette zone d’accueil s’allongent. L’étude...

L'alimentation et surtout la forme de présentation des aliments pour lapins constituent une des contraintes majeures en cuniculture. L'effet de 2 formes de présentation (granulé =G ou farineux = F) d'un aliment sur la croissance de lapereaux de souche locale en engraissement a été étudié au Nord-Bénin. Pendant 6 semaines, deux lots G et F de 48 lap...

The food of rabbits constitutes one of the major constraints in rabbit breeding. To mitigate this constraint, the valorization of the by-products locally available can be considered. This trial aims at determining the effect of soybean meal substitution by okara, in fattening rabbit feed, to reduce feeding costs. 144 locals rabbits aged 41 ± 2 days...

RESUME Cette étude vise à comprendre les pratiques de gestion des ressources pastorales des éleveurs bovins transhumants dans deux zones d’accueil au Bénin (Djidja et Tchaourou). A Djidja, deux arrondissements (Dan et Setto) et à Tchaourou deux zones de flux de troupeaux (Forte : FOT et faible: FAT de transhumance) ont été étudiées. Les activités d...

The objective of this study was to establish weight estimation equations from body measurements applicable to Lagune cattle. Live weight (LW), body length (BL), heart girth (HG), and withers height (WH) were recorded in 909 Lagune cattle (506 males and 403 females) aged from 0 to 45 months at the Samiondji Breeding Farm in southern Benin. The corre...
